uniform accleration

• Uniform acceleration


  A constant rate of acceleration, such as an object in free fall
• v² = u² + 2ax

  The equation linking final velocity, initial velocity, acceleration and distance

  
• v


  The symbol for final velocity
• u


  The symbol for initial velocity
• a

  The symbol for acceleration
• x


  The symbol for distance
• Metres per second (m/s)

  The SI unit for speed and velocity
• Metres per second squared (m/s²)

  The SI unit for acceleration
• Metres (m)


  The SI unit for distance
• Free fall


  The motion of a falling object when the only force acting on it is gravity

  
• Acceleration due to gravity

  Any object in free fall has an acceleration of about 9.8 metres per second squared (m/s²)
• Terminal velocity


  The constant velocity of a falling object when the resultant force acting on the object is zero and the object no longer accelerates
